Fill engine oil

The engine is shipped from the factory without
engine oil. If your dealer did not fill the oil, you
must fill it before starting the engine. NOTICE:
Check that the engine is filled with oil be-
fore first-time operation to avoid severe
engine damage.
[ECM01781]
The engine is shipped with the following stick-
er, which should be removed after engine oil
is filled for the first time. For more information
on checking the engine oil level, see page 45.

Breaking in engine

Your new engine requires a period of break-in
to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-
sure proper performance and longer engine
life. NOTICE: Failure to follow the break-in
procedure could result in reduced engine
life or even severe engine damage.
EMU40060
Procedure for 4-stroke models
Your new engine requires a period of 10
hours break-in to allow mating surfaces of
moving parts to wear in evenly.
TIP:
Run the engine in the water, under load (in
gear with a propeller installed) as follows. For
10 hours for breaking in engine avoid extend-
ed idling, rough water and crowded areas.
1. For the first hour of operation:
Run the engine at varying speeds up to
2000 r/min or approximately half throttle.
2. For the second hour of operation:
Run the engine at 3000 r/min or at ap-
proximately three-quarter throttle.
3. Remaining 8 hours:
Run the engine at any speed. However,
avoid operating at full throttle for more
than 5 minutes at a time.
4. After the first 10 hours:
Operate the engine normally.

Fuel level

Be sure you have plenty of fuel for your trip. A
good rule is to use 1/3 of your fuel to get to the
destination, 1/3 to return, and to keep 1/3 as
an emergency reserve. With the boat level on
a trailer or in the water, check the fuel level.
For fuel filling instructions, see page 48.
